The x coordinate ,
Do what you ALREADY KNOW HOW to do...
-----------That is one of them. Now can you find y?

y=-19
Answer by fractalier(6550) (Show Source): You can put this solution on YOUR website!
That's the correct start...now multiply both sides of each by two and get
x+8 = 4 and y+5 = -14
x = -4 and y = -19
The other endpoint is (-4, -19).

. Multiply each side by 2.
. Subtract 8 from both sides
.
The x value is -4.
.
.
The y value is -19.
